    摘要: The present invention relates to a concentrator for focusing solar radiation, having surface structuring in the form of one or more Fresnel lenses on the lower side, and to the production thereof from polymeric materials by means of a specific extrusion process. The inventive concentrator can be employed in plants utilizable for photovoltaic or solar heating purposes, and has the required durability and performance in demanding climatic zones. The inventive concentrator enables particularly economic production and efficient concentration of solar radiation onto objects such as solar cells or absorber units, irrespective of the geometry thereof. The inventive concentrator has high longevity and—combined with this—high optical performance when employed in extreme and demanding climatic zones. This relates, for example, to the area of a high-performance solar cell used in concentrating photovoltaics, and likewise to an absorber tube which finds use in concentrating solar thermal collector, for example in the context of parabolic trough technology.
